The Wishbone project

[Beezil]

Here's some various pics.......

this is an older "imaginary version" the links are MUCH higher now...

the link layout, including the wishbone and original joint idea

the rest of these are detail pictures of the joint, which the success of the design decides wether I wheel for an hour in moab and get laughed at (that will happen anyway) while hinkley welds my shit for corona, or I keep ridin' and see what happens next....

I like the string, are you going to do a write up on that mod. :D

[Dazz]

Where did you purchase the joints?

[Beezil]

I made them

[BrettM]

I like the tapered bearings and all, but why not just use a Johnny Joint or a 1.25" rod end mounted with the bolt verticle?

are you doing anything majorly different than Wanderingwillys (thats what he goes by on PBB, forget what he goes by here...), are you planning on hydro-assist (or full hydro), I remember wanderingwillys saying he needed it with his.

[BrettM]

oh baby! I just noticed the Krawlers!! nice:cool:

[PNWXJ]

Beez..I like it looks great! I too like the tapered bearing joint you made I am wanting to build one like that for my rear bumper/tire carrier pivot.

Using a JJ as the single pivot point from what I have heard is just not strong enough for this. There are alot of varied forces on this joint that the JJ or a heim cannot handle in one.

One ton can probably comment on the rod end survival expectancy....as for the johhny, they are not designed to control energy in t he plane that I need them to.....when positioned int eh plane that they ARE designed to work in, they do not offer enough articulation for this design....

as for wandering willys, I'm not sure what he is running........however, he might be the guy that one ton was talking about during a conversation about wishobone joints....he mentioned someone modifying a trailer hub or something like that....if wandering willys is that guy, than yes, this joint idea was directly inspired by his hub idea, so....my hats off to the man.

[BrettM]

wasn't it wanderingwillys that had a 3/4" rod end break and then he replaced it with the hub thingy? I don't think you would be breaking a 1.25" rodend, those things are about as big as your hand! I saw one used on a front upper wishbone on a heavy buggy with a big-block ramjet whatever and that monster rod-end just laughed at it.

[BrettM]

how many degrees of misallignment do JJs allow? for the big 3" Currie ones?

[Beezil]

I have no idea.......

look at this this way:

it didn't take me long to spin tat stock on my lathe, and the damn thing has 360 degrees worth of articulation!

dig that!

I realize that some of the things I end up with are not always the most direct, time-saving, or logical!

:D

First off OT needs to learn what size rod end to use, 3/4" is not the correct one, as he found out.

Yes, this is out of pure experience, the JJ from Currie can survive, even comp type abuse, on a side load. ie using it on a trianglated 3 link arm. (Yes I said three link, wishbone if you want)
However, I wouldn't put it on a daily driver with a side load, but then neither would I do a tri-3 link/wishbone on a daily driver. Yes Beezil I know you're not building a DD I just wanted to be clear about the conditions on which I would push/use a particular set up.

Beezil,

Nice joint, but a question for you... How are you going to keep the dirt and sand out of the bearings?

Beezil,

Looking back at those pictures I did notice that axle is WWWWAAAYYYYY to nice looking to be under your rig... So another question who's rig is that?:D


hinkley

[Beezil]

the two washers have around .005 clearance between the joint. I know that is enough to let moab silt in, but eveone knows, once you mix moab silt with water, you get a high-quality, natural, clay-based grease!

perhaps adding a zerk will help force out the other junk.....

[Beezil]

WWWWAAAYYYYY to nice looking

you didn't perhaps, find evidence of welding did you?

I promise markie mark, I will remember to weld ***all*** my brackets on this year

[BrettM]

so is it getting hydro steering? (assist or full)

[Flowers]

Damn B, that's lookin' tight yo!

[XJguy]

Beezil, go to the Timkin site, enter your specs and look up the sealed bearings you need. I have some sweet items on the prototype bench which I will debute in Moab, I used Timkins site extensively...hint hint hint.

Nice work..wish I had the machinerey you have access to, I would be probably building a space craft by now!

Looks like a good start. Somebody needs to get you a 'trial' version of AutoCad to help you save trees. Nice work on that link. Trailer axles have been used for the center axle mount before, are sealed and have tapered bearings. They aren't home-made though, some peeps have way too much time on their hands, you can get them from www.rockstomper.com.

Nice work Beez.

[JJ13]

At my old job we used bearings similar to those in the rolls for our tooling. If you find a seal to fit the housing holding your bearing and install the seal backwards you can grease the shiat out of it until your grease comes out clean. We had to do this every 8 hours and it greatly extended the life of our bearings. Or just install the seals like normal and replace the bearings every year.
That is some nice looking work BTW. :D

P.S. If you or anyone else needs a "trial" version of Autocad or Solidworks let me know.

I have an Academic version of Solid Edge (very similar to Solidworks, but better in my opinion) that I would be willing to copy and send on a CD to anyone who wants it. It states in the liscense that you can't use it for a business, blah, blah blah... I could probably get in trouble for "selling" it, but I would take a few bucks for the CD and shipping and "handling"

Solid Edge has a 3D part modeling application, an assembly application, draft, sheetmetal, weldment, and it is compatible with many other CAD programs.

Me, me I'll take one. :)

[Georgia Mike]

Hey Beez! When you clock in do you actually work on anything else besides stuff for your rig (EI:Stuff that makes everyone else here drool)? :laugh:

[JJ13]

send me a pm with your address JNJ :D

[4ward]

You better tighten up them ujoint straps before you wheel that thing.

I gotta question, how many dumb irishmans boots does it take to position an axle?

Mr. Hinkley, I think that the 3/4 would work if it were mounted in the horizontal plane instead of vertical. What was I thinkin :rolleyes:

That being said, I'm stepping up to a 1.25x1.00 heim just so I can use your welder on something else without you pissin' at me about tiny heims.

I'm also redesigning my front but it will still remain the same basic design. I'll have better clearance and better angles though.

[Beezil]

why is it when you break a self-fabricated part, that hinkley-guy is always the closest witness?

one-ton, I think we need to distance ourselves.....

[KY Chris]

Are you gonna use those joints for the spinning drum cage on the Fat Melinda World Tour 2004?

[Beezil]

Dude, i haven't got the time to work those issues out.....i thought you wanted me to get Gallegher to do the show opener?

http://gallaghersmash.com/images/king.jpg

I can't do everything......

Beezil,

That is just the way it works.
